[PATCH 1/2 RE-SEND] ARM: MM: Add ARM_L1_CACHE_SHIFT_6 for handle inside each ARCH Kconfig

[Kukjin Kim]

This patch adds ARM_L1_CACHE_SHIFT_6 into arch/arm/Kconfig. Basically,
ARM L1 cache line size is 32Bytes. Therefore, whenever new ARCH which
has 64Bytes L1 cache line size is added, have to set ARM_L1_CACHE_SHIFT
to 6. That is, have to add/modify arch/arm/mm/Kconfig.
This patch is for handle it in each ARCH such as ARCH_S5PC1XX, and
ARCH_S5PV210 which is in review.

A couple of comments:

1) Change ARCH_OMAP3 to use this
2) Could ARM_L1_CACHE_SHIFT_6 go before this, or is there an ordering issue?
